We present the use of a serial ring resonator system for multichannel radio frequency generation that can be used to form the radio frequency identification (RFID) application. A system consists of a serial nonlinear microring resonator system for generating pulse and selecting signals that can be filtered by using the add/drop filter. The input pulse is a Gaussian pulse with center wavelength at 1,500 nm. By using suitable simulation microring parameters, the generation of signal with the center wavelength or frequency at 2.15 nm or 285 GHz is achieved, where the high frequency RFID with 91 channels is generated and noted. The use of THz frequency enhancement and RFID-based wireless communication is discussed. © 2012 Wiley Periodicals, Inc.

A new design of THz frequency carrier generation for radio frequency identification (RFID) application is presented. The dense wavelength division multiplexing can be generated and obtained by using a Gaussian or soliton pulses propagating within a modified add-drop filter known as a PANDA ring resonator. A system is consisted of a serial nonlinear microring resonator system. The broad bandwidth of THz signals can be obtained and available for useful applications. The selected signals can be filtered and obtained by using the add/drop filter. Results obtained have shown that the increasing in channel capacity can be obtained and useful for the large demand of RFID applications. © 2012 Wiley Periodicals, Inc.

We propose the interesting results of high frequency generation method, which is required to use in the THz regime. A generated system consists of two micro and a nano rings that can be integrated into a signal system which can be employed to generate the large bandwidth by a Gaussian pulse propagating within the ring resonator system. The selected signals can be stored and filtered by using the optical storage unit and an add/drop filter, respectively. By controlling the ring parameters, the appropriate output power can be obtained, which can be modified to be suitable in either imaging or communication applications. Moreover, the very wide band of wavelength can be generated and controlled for various applications. © 2010 Elsevier GmbH. All rights reserved.
